The area of a triangle is
A=bh/2 where b=base and h=height. So we first have to solve for h
8^2+h^2=12^2
h^2=12^2-8^2
h^2=144-64
h^2=80
h=(80)^(1/2), now we can find the area
A=8(80^(1/2))/2
A=4(80^(1/2)
A=35.78cm

Lucas is making a wire sculpture for art class. For the sculpture, he needs to cut a wire into pleces that
are each 1/16 of a foot long. If the original wire is 3/4 of a foot long, how many pieces will Lucas have?
⟹Answer:
➧Lucas can cut the wire into 12 pieces.
Step-by-step explanation:
⟹Lets Solve!
⟹The first step is to convert \(\frac{3}{4}\) into \(\frac{}{16}\) !
To do this we must find what number multiplied by 4 equals 16.
16 ÷ 4 = 4
⟹Now we know our multiplier is 4. So lets multiply the numerator and denominator by 4.
\(\frac{3}{4} * \frac{4}{4} = \frac{12}{16}\)
\(\frac{12}{16}\)
⟹Next we just divide \(\frac{12}{16}\) by \(\frac{1}{16}\).
\(\frac{12}{16}\) ÷ \(\frac{1}{16}\) = 12
➧Lucas can cut the wire into 12 pieces.
Woohoo! Brainliest appreciated! Hope I helped!
Based on the original length of the wire and the length Lucas requires, he will have 12 pieces.
The wire is 3/4 feet long and each piece required will be 1/16 feet.
The number of pieces in total is:
= Length of wire / Length of pieces
Solving gives:
= 3/4 ÷ 1/16
= 3/4 × 16/1
= 48/4
= 12 pieces
In conclusion, Lucas will have 12 pieces.

What is the volume of a hemisphere with a radius of 44. 9 m, rounded to the nearest tenth of a cubic meter?.
The volume of a hemisphere with a radius of 44.9 m is approximately 189582.2 cubic meters, rounded to the nearest tenth.
To calculate the volume of a hemisphere, you can use the formula
V = (2/3)πr^3
where V is the volume, π is pi (approximately 3.14), and r is the radius. In this case, r = 44.9 m.
So, (2/3)π(44.9)^3 = 189582.234 cubic meters.
This is the exact volume, but since the question asked for the volume rounded to the nearest tenth, the final answer would be 189582.234 cubic meters. It's worth mentioning that a hemisphere is half of a sphere, thus, the volume of a full sphere with a radius of 44.9 m would be double of this value.

What is the solution set of {xlx<-3}{xlx>5)?

all numbers except -3 and 5
the empty set
the numbers between -3 and 5
Explanation:
The first set {x | x < -3} means we're talking about numbers smaller than -3. This includes -4, -5, -6, etc
The second set {x | x > 5} means we're talking about numbers larger than 5. So things like 6,7,8,...
Combining both at the same time, we want to find a number that is both smaller than -3 and larger than 5. This is impossible as no such number exists. You can pick one or the other, but not both.
There are no solutions. Since there are no solutions, the solution set is the empty set.
how long is the arc intersected by a central angle of radians in a circle with a radius of 2 ft? round your answer to the nearest tenth. use 3.14 for .
The length of the arc intersected by a central angle of radians in a circle with a radius of 2 ft is approximately 5.2 ft. The central angle is given as radians and the radius of the circle is 2 ft
To find the length of the arc intersected by a central angle, we can use the formula:
Length of arc = (central angle / 2π) * 2πr
Given that the central angle is in radians, we can plug in the values into the formula:
Length of arc = (radians / 2π) * 2π * radius
In this case, the central angle is given as radians and the radius of the circle is 2 ft. So, we have:
Length of arc = ( radians / 2π) * 2π * 2
Simplifying this expression, we can cancel out the 2π terms:
Length of arc = radians * 2
To round the answer to the nearest tenth, we need to calculate the value of the given central angle in radians:
radians = 150 degrees * π / 180
After substituting the value of radians in the formula, we get:
Length of arc = (150 * π / 180) * 2
Now, we can calculate the value using the approximation of π as 3.14:
Length of arc = (150 * 3.14 / 180) * 2
Length of arc = 5.24 ft (rounded to the nearest tenth)
Therefore, the length of the arc intersected by a central angle of radians in a circle with a radius of 2 ft is approximately 5.2 ft.

Use point-slope form to write the equation of a line that passes through the point
(-7, 10) with slope -5.
Answer:
y = -5x - 25
Step-by-step explanation:
Substitute into form of y - y1 = m(x - x1): (Take the point (-7,10) for x1 & y1, m would be the slope)
y - 10 = -5(x -(-7))
y - 10 = -5(x + 7)
y - 10 = -5x - 35
y = -5x - 25
Answer:
y= -5x-25
Step-by-step explanation:
Equation of line with points given =
y = mx + b
m = -5 , x = -7 , y = 10 while the intercept, b is not given, so we need to find that...
Therefore, we substitute the value for the given equation
10 = -5*-7 + b
10 = 35 + b
b = 10 - 35
b = -25
Therefore we substitute the value for m and b to the equation of line

The city decided to reduce taxes over the next two years. They will reduced
taxes 5% the first year and 4% the second year. What will be the total percent
reduction in taxes? Do not round the final answer.
The total percentage reduction in taxes over the two years is 9%.
We must determine the cumulative effect of the tax cuts in order to determine the total percentage reduction in taxes over the two years.
To begin, how about we determine the first-year duty reduction of 5%? This demonstrates that the charges will be reduced to 95% of the underlying amount, or 5% short of 100%.
An additional 4% will be cut from taxes for the second consecutive year. This indicates that the duties for the following year will be 91% of the amount that was reduced in the previous year, or 95% to 4%.
The complete decrease in charges is determined utilizing the rate distinction between the last duty rate (91%) and the underlying expense rate (100 percent).
As a result, the total tax cut over the next two years is 9%. (Original tax rate - Final tax rate) / Original tax rate x 100 percent Total percentage reduction = (100 percent - 91 percent) / 100 percent x 100 percent Total percentage reduction = 9 percent

At Discovery Preschool, parents who have two students enrolled get a discount on the second child. The second child's tuition is 10 dollars less per day than the first child's if Tess has her two children enrolled for 5 days her total bill for both children is $200, how much does she pay each day for her second child to attend daycare
The tuition of the second child will be $95 per day.
Let the tuition of the first child be x.
So, the tuition of the second child will be (x - 10).
As per the given condition:
Tess has her two children enrolled for 5 days her total bill for both children is $200.
Hence, the total tuition of both children is $200.
∴ x + (x - 10) = 200
⇒ 2x - 10 = 200
⇒ 2x = 200 + 10 = 210
⇒ x = 105
So, the tuition of the first child is $105 per day.
Thus, the tuition of the second child will be $(105 - 10) = $95 per day.

1. The probability of selecting exactly one tank with high-viscosity material is 0.
2. The probability of selecting at least one tank with high-viscosity material is 1.
3. The probability of selecting exactly one tank with high-viscosity material and exactly one tank with high impurities is 0.25.
1. The probability of selecting exactly one tank with high-viscosity material is calculated by the binomial distribution formula, P(X = n) = (nCx)p^x(1-p)^n-x, where n is the number of trials, x is the number of successes, and p is the probability of success. In this case, n = 4, x = 1, and p = 24/24 = 1. Therefore, P(X = 1) = (4C1)1^1(1-1)^4-1 = 0.
2. The probability of selecting at least one tank with high-viscosity material is calculated by the complement rule, P(X > 0) = 1 - P(X = 0). In this case, P(X > 0) = 1 - (4C0)1^0(1-1)^4-0 = 1.
3. The probability of selecting exactly one tank with high-viscosity material and exactly one tank with high impurities is calculated by the binomial distribution formula, P(X = n) = (nCx)p^x(1-p)^n-x, where n is the number of trials, x is the number of successes, and p is the probability of success. In this case, n = 8, x = 2, and p = 24/24 = 1. Therefore, P(X = 2) = (8C2)1^2(1-1)^8-2 = 0.25.

The position vector r (with components x1, x2, x3) and any vector v can be expressed as r = x1*i + x2*j + x3*k and v = a*i + b*j + c*k, respectively.
How can we show that the dot product of the position vector r and the vector v is equal to the sum of the products of their corresponding components?The dot product of two vectors is defined as the sum of the products of their corresponding components. Therefore, the dot product of r and v can be calculated as:
r · v = (x1*i + x2*j + x3*k) · (a*i + b*j + c*k)
= (x1*a) + (x2*b) + (x3*c)
